char

问题 Is there a better way of the following for concatenating items in a list that are "integers" into a string: import numpy as np my_list = [1, 1, 0, 0, 0, 0, 1, 1, 1, 0, 1, 0] changed_list = np.char.mod('%d', my_list) final_ans = ''.join(changed_list ) 回答1: Im not sure what you mean by better, but you could try this. ''.join([str(x) for x in my_list]) 回答2: how about this? ''.join([str(item) for item in my_list]) 回答3: You can use the bitstring module: >>> from bitstring import BitArray >>> f'

问题 At the end of my loop, I am planning on displaying the number of consonants and vowels in the sentence. I was wondering if there was a more efficient way to check how many consonants and vowels are in a given sentence, rather than using an if statement and manually inputting every letter. (key refers to my Scanner which has already been initialized) Edit: It needs to ignore digits and other special characters, so for example if I write Hello@ how 1are you?. There should be 8 vowels and 6

问题 I am facing with this unwanted char to int conversion in a loop. Say I have this List of Characters and I want to remove one of those: List<Character> chars = new ArrayList<>(); chars.add('a'); chars.add('b'); chars.add('c'); chars.remove('a'); // or chars.remove('a'-'0'); so 'a' is interpreted as its int value and I'm getting an IndexOutOfBoundsException exception. Is there any easy workaround for this? 回答1: A char is promoted to an int , which takes precedence over autoboxing, so remove(int

问题 I am trying to call C methods from Python script but I am facing an issue while calling the method which outputs char** array as an argument. the method in C layer as follows. helper.c file: //This method takes filename as input and oNames as output extern C int GetNames(char* iFilename, char** oNames) { int oNumNames, oStatus; /*io* pIo = GetIoInstance();*/ std::vector<EString> names; CreateIoInstance(iFilename); oStatus = pIo->get_names(names); oNumNames = (int)names.size(); for (int ii = 0

问题 I have 60 different character arrays (Book01, Book02, ..., Book60). (For example Book01 is a 1x202040 char.). I want to do a certain procedure only on Book45 until Book58. How do I write an IF-statement or FOR-loop, so that the procedure is only performed for character arrays Book45 until Book58? For example: Book05 % Inserted Array for test if Book45|Book46|Book47|Book48|Book49|Book50|Book51|Book52|Book53|Book54|Book54|Book56|Book57|Book58 % If inserted array is Book45-58 % Procedure to be

问题 I am trying to write a program that copies its input to its output. I am assuming that if I am given the following string: "Hello I am /c" it should output: "Hello \t am \c" am I correct? I have tried reading online about the stdio.h library. #include <stdio.h> /* Write a program to copy its input to its output, replacing each tab by \t, each backspace by \b, and each backslash by \\. This makes tabs and backspaces visible in an unambigous way.*/ int main() { char c; while ((c = getchar()) !=

问题 I'm currently trying to split an array of chars that is assigned from reading in from a text file. right now I'm having troubles with delimiters and I don't know if I can have multiple. what I want to delimit is commas and spaces. Here is my code so far. #include <stdio.h> FILE * fPointer; fPointer = fopen("file name", "r"); char singleLine[1500]; char delimit[] = int i = 0; int j = 0; int k = 0; while(!feof(fPointer)){ //the i counter is for the first line in the text file which I want to

问题 This question might be asked before but I couldn't find exactly what I need. My problem is, I have a buffer loaded by data downloaded from a webservice. The buffer is in unsigned char* form in which there is no '\0' at the end. Then I have a poco xml parser needs a string. I tried assigning it to string valgrind found some lost data. (see below) here is the code: DOMParser::DOMParser(unsigned char* consatData, int consatDataSize, unsigned char* lagData, int lagDataSize) { Poco::XML::DOMParser
